Listen to the episodeAbout Caudal Energy
Caudal Energy is an Oxford spinout based on hydrodynamics research and focused on a new architecture for tidal power. Its technology aims to overcome the limits of traditional turbines by operating in mid-flow sites with a modular design that is simpler to install and maintain. The Caudal Generator, an oscillating-foil tidal platform, targets distributed energy, industrial and utility markets, competing with tidal turbine developers and marine energy platforms. The £4.3M round funds technology development.
The Story
Founded in 2024 as Porpoise Power, based on research by co-founder Professor Adrian Thomas at the University of Oxford.
